The patient's hemodynamic parameters are most consistent with hypovolemia.The renal failure would then most probably be prerenal from inadequate blood flow.The treatment of choice for hypovolemia is fluid resuscitation.Important criteria when calculating fluid volume replacement include baseline metabolism, environmental temperature, and humidity.The rate of replacement depends on cardiopulmonary reserve, adequacy of kidney function, urine output, fluid balance, ongoing loss, and type of fluid replaced.
